If this is true, why don’t we disable/hide the block size dropdown for platforms which don’t use it? > On Apr 20, 2017, at 1:13 AM, pd-list-request(a)lists.iem.at wrote: > > From: Lucas Cordiviola <lucarda27(a)hotmail.com <mailto:lucarda27@hotmail.com>> > Subject: Re: [PD] pd 0.47.1 Changing Block Size in Audio Settings hangs program > Date: April 19, 2017 at 10:23:48 PM MDT > To: Leo Wang TIC-work <leointic(a)hotmail.com <mailto:leointic@hotmail.com>>, "pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>" <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > > > Hi, > > Iirc Pd's preferences “Block Size” is only meant to be used with ASIO drivers on MsWindows. > This setting controls the buffer size of your ASIO driver. > > Salutti, > Lucarda. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

pd 0.47.1 Changing Block Size in Audio Settings hangs program
by Leo Wang TIC-work 20 Apr '17

20 Apr '17

It is possibly a bug. OS: Mac OSX 10.11.6 Problem: when change the default value from 64 to 128. the program hangs. and you have to force quit PD. And the CPU utilisation shot to 100%. same thing happens on Windows10 pd0.47.1 Many thanks Leo

Re: [PD] nqpoly~ and dynamic object generation, loadbang issue?

Christof, thanks for the [initbang] tip. I could find [init] but it doesn't seem to do the same thing. After downloading iemguts, I don't see [initbang] inside. Is it gone now? I'm running Pd vanilla 0.47.1 on a Mac.

some GEM questions ...
by oliver 20 Apr '17

20 Apr '17

hi, dear list ! i'm looking for an insight into some questions i ran into recently when i decided to give GEM a serious shot after all. please be patient, i'm probably spoiled by JITTER ... PD 0.47.1 GEM 0.93.3 WINDOWS 7/64bit 1.) is there a way to do image processing (i.e. levels, contrast, satturation etc.) on the GPU ? as far as i understood [pix_...] objects do all their processing with the CPU and others like [color] do it in openGL (thus GPU), is that right ? now, for big textures (1280x720 or bigger) that would be the preferable way of manipulating things, right ? 2.) i'm looking for objects that do "compositing", i.e. ways to overlay two pix sources. apart from the ones existing (add, multiplay, subtract, mix) , i would love to have the well-known (AE,vegas, etc.) compositing modes like "darken", "lighten", "dodge" "difference" etc. - but also chromakeying ! is this possible ? and is it possible to do in opengl rather than with a [pix_] object ? 3.) concerning shaders: documentation here is quite sparse and no GLSL example patch works on my machine the PD window says just this: [glsl_vertex]: error reading file [glsl_fragment]: error reading file is my graphics card not up to it ? 4.) are there any GEM GLSL shaders collections around ? i didn't really find anything useful. again i am basically searching for compositing shaders (like the ones that VADE made for Jitter some years ago) and something like brightness, contrast, saturation etc.) thanks for any hints and helps ! best oliver

JAVA sockets
by Billy Stiltner 20 Apr '17

20 Apr '17

if you are like me and use JAVA sockets from firefox to communicate between PD and javascript this might help. icedteaweb-plugin doesn't load in firefox 52 from firefox ,browse to about:config right click to add a new boolean name: plugin.load_flash_only value: false now what to do to replace JAVA with something as cross platform in the way of a websocket server or "other thing" that will be sure to still be working 20 years from now?

[PD-announce] Context sequencer, beta release and call for participation
by Liam Goodacre 20 Apr '17

20 Apr '17

Dear PD community I am happy to announce the beta release of Context, a powerful new sequencer for PD. Context is a modular sequencer that re-imagines musical compositions as a networks. It combines traditional step sequencing and timeline playback with non-linear and algorithmic paradigms, all in a small but advanced GUI. Unlike most other sequencing software, Context is not an environment. It is a single abstraction which may be replicated and interconnected to create an environment in the form of a network. There are literally endless possibilities in creating Context networks, and the user has a great deal of control over how their composition will function. >From a technical perspective, Context features a lot of things that you don't often see in PD, such as click + drag canvas resizing, dynamic menus, embeddable timelines, and fully automatic state saving. It also boasts its own language, parsed entirely within PD. Context is work in progress--there are still lots of bugs in the software and lots of holes in the documentation. However, I have gotten it to a place where I feel it is coherent enough for others to use it, and where it would benefit from wider feedback. I am especially looking for people who can help me with proof reading and bug tracking. Please let me know if you want to join the team! Even if you can't commit to much, pointing out typos or bits of the documentation that are confusing will be very helpful to me. Some notes on the documentation: I have been putting 90% of my efforts recently into writing the manual, and only 9% into writing the .pd help files (the remaining 1% being sleep). The help files are pretty, but the information in them is not very useful. This will be corrected as soon as I have more time and better perspective. In the mean time, please don't be put off by the confusing help files, and treat the manual as the main resource. Context is available now at https://github.com/LGoodacre/context-sequencer.<https://github.com/LGoodacre/context-sequencer> A few other links: * The debut performance of Context at PDCon16~: https://www.youtube.com/watch?list=PL6f_f6nYVx1f1TdAa58418kk5K9bWJ7pm&v=poW… <https://www.youtube.com/watch?list=PL6f_f6nYVx1f1TdAa58418kk5K9bWJ7pm&v=poW…> * An explanation of this performance: http://newblankets.org/liam_context/context-patch.webm <http://newblankets.org/liam_context/context-patch.webm> * A small demo video: https://www.youtube.com/watch?v=5_eLOGA7Ado * My paper from PDCon16~: https://contextsequencer.files.wordpress.com/2016/11/goodacre-context.pdf <https://contextsequencer.files.wordpress.com/2016/11/goodacre-context.pdf> Finally, I should say that this project has been my blood sweat and tears for the past 18 months, and it would mean a great deal to me to see other people using it. Please share your patches with me! And also share your questions--I will always be happy to respond. I would like to thank the PD community for their support and inspiration, in particular Joe Deken and the organizers of PDCon16.

Re: [PD] [PD-dev] line object (non tilde version)

If you need a continuous ramp, you definitely want to use [line~] and not [line]. You may also want to read about messages (chapter 2.3) and signal domain (chapter 2.4) in the Pd documentation.

nqpoly~ and dynamic object generation, loadbang issue?
by Samuel Burt 17 Apr '17

17 Apr '17

Dear List, I'm zeroing in on a problem I'm having. If you've got some experience with this, please, help me out. I *dynamically create* copies of an abstraction in a patch that *contains [nqpoly~]*. The abstraction [nqpoly~] contains a *[loadbang]* that is supposed to trigger the creation of its polyphonic voices. From experimentation and researching online, it seems that *[loadbang] doesn't trigger* when created *within a dynamically generated abstraction*. How do I get [nqpoly~] to create its voices? Thanks, Sam
